    Growth and yield of lettuce under Kratky hydroponics using coco peat mixed with charcoal and oyster shell as growing media
    Cañedo, Ranel A. (Davao del Sur State College, 2024-06)
    A study was conducted in March in sitio Balutakay Managa, Bansalan, Davao del Sur to investigate the growth and yield of lettuce using Kratky hydroponics. The growing media consisted of cocopeat mixed with charcoal and oyster shell. This study employed a Completely Randomized Design (CRD) consisting of three (3) treatments and five (5) replications. Specifically, the purpose of this research was to identify the growth and yield of lettuce under Kratky hydroponics using cocopeat mixed with charcoal and oyster shell as growing media in terms of plant height, number of leaves, root length and yield. In terms of plant height, treatment 1 (87.5% (266 g) cocopeat, 7.5% (22.8 g) charcoal, 5% (15.2 g) oyster shell) had the highest mean height with (20.240 cm) while treatment 2 (82.5% (250.8 g) cocopeat, 7.5% (22.8 g) charcoal, 10% (30.4 g) oyster shell) had the lowest mean height with 19.508 cm. In number of leaves, treatment 1 (87.5% (266 g) cocopeat, 7.5% (22.8 g) charcoal, 5% (15.2 g) oyster shell) had the highest number of leaves with (14,000 cm). In root length, treatment 2 (82.5%), (250.8 g) cocopeat, 7.5% (22.8 g) charcoal, 10% (30.4 g) oyster shell) had the highest mean root length with (20.624 cm) while treatment 3 (77.5%) 5.6 g) cocopeat, 7.5% (22.8 g) charcoal, 5% (15.2 g) oyster shell) had the highest mean plant yield with (0.121 kg) while treatment 2 (82.5%), (250.8 g) cocopeat, 7.5% (22.8 g) charcoal, 10% (30.4 g) oyster shell) had the lowest mean of (0.109 kg).

    Acceptability level of banana (Musa balbisiana) and calamansi (Citrus microcarpa) peels as alternative floorwax
    Rosit, Khitterine Fel l. (Davao del Sur State College, 2024-03)
    The objective of the study was to determine the acceptability-level of Davao del Sur State College’s Banana (Musa balbisiana) peels and Calamansi (Citrus microcarpa) peels as alternative floor wax. It was an invention product that could be further recycled into an item of excellent quality that would be valuable to families in terms of appearance, color, odor, slip-resistance and water-resistance. This research comprises five treatments and will have thirty participants. Demonstration of product innovation and a use of complete randomized design and a survey questionnaire with a predetermined rating scale using a Likert Scale of 1.00 to 5.00 was use to collect the data. The results of a descriptive-comparative research approach and analysis of variance (ANOVA) revealed that banana (cardava) and calamansi peels was more acceptable and treatment 3 had the highest mean and verbal description of being the most acceptable and ii valued by the respondents. Therefore, Treatment 3 is the best as it most acceptable than the control group in terms of the sensory characteristics conducted appearance, color, odor, slip-resistance and water-resistance. As a result, it may be improved and adapted for commercialization, thereby rendering it more appealing to buyers. Innovations and development of banana and calamansi peels as alternative floor wax are highly encouraged. It was recommended to use proper and accurate textile or fabric of rag in applying this alternative floor wax, and it was suggested, which is considered a major issue for environmental and green ecology, that this waste is dumped in landfills, contributing to pollution problems and environmental issues. Finding solutions to the world, particularly the Philippines, environmental problems as a result, this is the crucial initial step in resolving it.
